I'd done a yearbook and it had this gold-leafing on the front with the logo and suchlike. Somehow I managed to actually aquire the die used to create the logo, the actual metal slab with the back-to-front logo embossed out of it. Nice. It had the name of the yearbook and the year embossed out so it could only be used once. It was about the size of your palm.
A while later, the institution asks whether I still had the die.
I said, "I do. Wwwwwhat do you want it for, exactly...".
They say, "We were considering using it for letterheads and stuff."
"Well, it's got the year embossed out of the metal plate and the name of the yearbook embossed out, as well."
"So we can't use it?"
"Not really, unless you want the year on each letterhead. It has the name of the yearbook on it too. It's probably too big anyway."
"I see. So you can't just resize it and get rid of the year? Why not?"
"....<sound of me choking a laugh>"
I tried hard, and failed, to prevent myself from laughing.
